The former France international only arrived in Rome a year ago from Girondins Bordeaux for €1.5m (£1.3m).

He was rarely first choice under Vladimir Petkovic, making 18 Serie A appearances, 12 in the Europa League and five in the Coppa Italia, where he also scored a goal. He still managed seven yellow cards and a red.

According to the latest reports from Sky Sport Italia, Celtic are prepared to pay €2m for Ciani (£1.7m).

As that would provide Lazio with a profit for the 29-year-old, it is very likely to go through successfully.
